I just checked out the PSU forums

I'd be depressed if PSU didn't suck as much as it did. It's emptier there than the classic forums.

Like most boom towns, if there's nothing to keep them going, they become ghost towns. Internet style.

And yet the PSO forum still seems healthy.

There's a ton of private servers for PSO still, whereas for PSU it is not so much the case. If PSU had lively (and functional) private servers I think the forums would be a little more lively.
